What is Slack?

Slack is a collaboration hub where you and your team can work together to get things done. From project kickoffs to budget discussions, and to everything in between — Slack has you covered.

Key features

💬 Organized conversations

In Slack, work happens in channels. You can create channels based on teams, projects, or even office locations. Members of a workspace or org can join and leave channels as needed.

🔎 Searchable history

When messages and files are shared in public channels, information flows transparently throughout Slack. Search is how you can narrow down and find what you need. Learn how to search for messages and files.

👥 Work with external partners

Shared channels and guest accounts give you the flexibility and freedom to work with clients, contractors and other third parties without having to leave Slack.

🤖 Apps and integrations

Apps and integrations are the tools that will help you to bring your existing workflows into Slack. The Slack App Directory has thousands of apps that you can integrate into Slack.

Your Slack workspace

A workspace is a shared hub made up of channels, where team members can communicate and work together. Small to medium-sized companies will typically share one workspace.

Larger enterprises may have an Enterprise Grid organization containing multiple interconnected workspaces. Share channels across these workspaces for things like company announcements and other information that is relevant to all employees.
